RAIL-JOINT.

Specification of Letters Patent.

Patented Jan. 3, 1911.

Application filed September 3, 1910. H Serial No. 580,331.

To all whom it may concern:

Be it known that I, MATHEWS JOHN KUTsoH, a citizen of the United States, residing at Tarentum, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specification, reference being had to the accompanying drawings.

1.0 My invention relates to improvements in the construction of railway rails whereby joints may be effected between the meeting ends of the rails and the rails may be securely connected together so that they cannot spread or become overturned, without the necessity of employing fish plates and bolts at the joints, the invention consisting in the construction and arrangement of devices hereinafter described and claimed.

In the accompanying drawings,Figure 1 is a perspective view of the meeting ends of a pair of rails constructed in accordance with my invention and showing a oint formed between the said rails, a tie being indicated on which the ends of the rails bear and one of the spikes which secure the rail ends on the tie being also shown. Fig. 2 is a side elevation of the same partly in section.

view of the same on a plane intersecting the projecting arm.

Each rail 1, which is otherwise of the usual form, comprising a base 2, vertical web 3, and head 4: is, in accordance with my invention, formed at one end of its head with a projecting arm 5, the upper side of which is flush with the upper side of the head, the rail being formed at its opposite end in its head with a recess 6 of a size and shape adapting the same to receive the pro j ecting arm of the next adjacent rail. Hence -the arm and recess of the meeting rails coact to effect a perfectly secure joint between them at the rail ends.

Owing to the fact that the arm is at the head of the rail and fits in the recess in the meeting end of the next adjacent rail, the arm, which is a portion of the head or tread of one rail overlaps the joint between therails, and the rail ends are thereby tied together so that stress occasioned by the Fig. 3 is a transverse sectional weight of a passing train will be equally distributed between the two rails when the train is passing over the joint between them, and neither rail will be depressed inde pendently of the other. Hence injury to the meeting ends of the rails will be ob viated, and moreover the overlapping connection between the heads of the rails greatly facilitates the passage of the train wheels from one rail to another and prevents jarring and jolting. Thus not only does my invention secure improved results as to the durability and efliciency of the rails, but also causes the cars to ride more easily and smoothly.

The side flanges of the bases of the rails are provided at their meeting ends with notches 6. Each of the said notches is formed partly in each of the rail base flanges. In connection with my improved rails I also employ spikes 7 for securing them on the cross bars,,one of which is indicated at 8. Each spike 7 is, in accordance with my invention, provided with a broadened head 9 providing end portions 10 which project from opposite sides of the shank of the spike, the extent of the head of the spike being such that the same bears on the base flanges of both of the rails at the joint between them. Hence the spikes serve to eflectually secure the rails on the ties.

Having thus described my invention, what I claim is In combination with the meeting ends of a pair of rails, rails provided in their base flanges with notches which are formed partially in the flanges of both of said rails, spikes to be driven into the tie on which the rail ends are located, the said spikes being provided with enlarged heads forming side extensions at the upper ends-thereof to bear on the base flanges of both of said rails, the said spikes being placed in the said notches of the said rails.

In testimony whereof I hereunto a'lfix my signature in the presence of two witnesses.
